I did not throw this in news because Ariel Helwani said it was unconfirmed, but on this week's The MMA Hour, Helwani said this:

"What I heard from one source, just one, was that it was a one year deal worth $20,000. That's what I heard, but I have not been able to confirm that with multiple sources. One source very close to Jon, by the way, I should say. It's not like it's just source you know out of the blue."
